Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom BS EN 12561-7:2011 EN 12561-7:2011 (E) Scope This European Standard applies to ladders, platforms and walkways on tank wagons fitted with top devices It does not apply to crossing gangways nor to steps in so far as they are covered by UIC leaflets This European Standard defines the important dimensions for manufacturers and operators of such tank wagons and takes into consideration the relevant and applicable construction and safety guidelines This European Standard applies to new tank wagons built after the 1st January 2010 In consideration of the smaller loading gauge within the UK, this European Standard does not apply to wagons operating exclusively therein Normative references The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies EN 795, Protection against falls from a height — Anchor devices — Requirements and testing EN 14564,Tanks for transport of dangerous goods – Terminology EN ISO 6346:1995, Freight containers — Coding, identification and marking (ISO 6346:1995) Terms and definitions For the purposes of this document, the terms and definitions given in EN 14564 and the following apply 3.1 platform level floor at the top of the tank for inspection, maintenance and operational purposes 3.2 walkway structure supporting grating to provide access between ladders and platforms 3.3 protective device device to deflect operating personnel from protruding parts of a moving tank wagon in accordance with UIC 535-2 4.1 Ladders General Where tank wagons are fitted with ladders, they shall either be fitted with one fixed ladder located at the end or with a fixed ladder on each side of the tank wagon NOTE The end ladder is usually fitted at the crossing gangway Ladders shall be fitted with lateral handrails BS EN 12561-7:2011 EN 12561-7:2011 (E) NOTE For traffic of continental tank wagons running in Great Britain, the kinematic gauge for Great Britain rules defined in the Technical Specification for Interoperability for freight wagons (TSI) also apply and to avoid conflict between these rules, local arrangement for handrail should be allowed to stay in the gauge The pitch of the ladder as shown in Figure shall be between 75° and 90° Where the pitch is less than 75° steps shall be used in place of rungs The depth of the steps shall be at least 80 mm Key Pitch Handrails String Rung Figure — Terms The rungs and the steps shall be welded to the strings and shall be slip-resistant Rung slip resistance can, for example, be achieved by using square or flat bars with a cross section as shown in Figure Figure — Examples of rung cross sections BS EN 12561-7:2011 EN 12561-7:2011 (E) If they are from square or rectangular section, they shall not have sharp edges Steps shall have a grating according to the requirements of Clause 4.2 Main dimensions The main dimensions of ladders shall be as shown in Figure and Figure All the rungs shall be equally spaced The sides of square steel rungs shall be between 20 mm to 30 mm Different shaped rungs of equivalent strength are permitted provided they are slip resistant (e.g rectangular steel rungs with a cross section of 40 mm × mm) The clearance above and behind each rung shall be as shown in Figure The handrail shall be made from circular cross section tubes or bars of at least 20 mm outside diameter The ladder handrail shall be connected to the toe plates of the walkways or platforms The clearance around the handrail shall be at least 100 mm Where lateral ladders protrude more than 250 mm from the chassis of the tank wagon, a protective device shall be fitted at a height of between 200 mm to 400 mm above the rail (see Figure 6) The lateral ladders shall not infringe the loading gauge 4.3 Design values Ladders shall be designed to withstand a static load of 2,0 kN in the centre of any rung The maximum allowable elastic deformation under this load shall not exceed 1/200 of the width 4.4 Marking A warning sign for overhead electrical danger shall be located near to each ladder in accordance with EN ISO 6346:1995, Annex C or Technical Specification for Interoperability for Freight Wagons BS EN 12561-7:2011 EN 12561-7:2011 (E) Dimensions in millimetres Key Top of crossing gangway Figure — Main dimensions of end ladders BS EN 12561-7:2011 EN 12561-7:2011 (E) Dimensions in

attached;  to have a grating according to the requirements of Clause The platform, including the toe plates shall not infringe the loading gauge The width of the platform and the height of the toe plates may need to be reduced for domestic traffic in Great Britain (see Technical Specification for Interoperability for Freight Wagons) BS EN 12561-7:2011 EN 12561-7:2011 (E) 5.2 Design values The platform shall be designed to withstand a load of kN uniformly distributed over an area of 600 mm × 300 mm The deflection under this load shall not exceed 10 mm or 1/200 of the span, whichever is the smaller 6.1 Walkways General Walkways shall be built in accordance with the following requirements:  to be flat and may have a maximum longitudinal slope of 5°;  to be surrounded by a toe plate of minimum 20 mm height, except where a ladder or a platform is attached;  to be fitted with a safety rail with a minimum clearance of 100 mm around it (see Figures and 4);  to have a grating according to the requirements of Clause It is recommended to have walkways at the same level as the platform 6.2 Main dimensions The width of the walkways shall not be less than 500 mm and shall not infringe the loading gauge The width of the walkways, the height of the toe plates and the clearance around the safety rail may need to be reduced for domestic traffic in Great Britain (see Technical

in three directions (lengthwise, breadthwise and diagonally) shall reach the following minimum values: a) in dry condition 0,65; b) in wet condition (water) 0,65; c) in oiled condition 0,30 Friction coefficient values shall be ascertained by means of a 100 mm × 100 mm movable plate, on which a rubber pad with 80 I.R.H.D hardness shall be glued; this plate shall be loaded to 750 N For the measurements carried out with water or oil, the grating shall be fully immersed 10 BS EN 12561-7:2011 EN 12561-7:2011 (E) 7.2 Grating structure To ensure that the gratings are sufficiently well adapted to winter conditions, a ratio of at least 50 % of void area to total area shall be observed Only apertures with a minimum area of 400 mm² shall be taken into account to determine this ratio The void area is the free space afforded, in the vertical direction, by the grating apertures Fixing Where ladders, platforms and walkways are fixed to the shell of the tank wagon, doubler plates shall be used The fixings shall be properly secured to discourage theft and minimise the risk of working loose The attachment of the ladder to the vehicle shall not introduce unacceptable stresses
